No, I don't measure disc run out. Again, it's not something I can correct that accurately. I can get an idea by spinning the wheel and feeling and how the brakes operate on the road.

 

If you knew what disc run out is you would realise that it is simple to correct and that with a good DTi you can correct it, simply rotate the disc on the drive flange and if that doesn't correct it rotate the drive flange on the CV assy you will find that there is a "best" fit that will invariably be within the distance set in the workshop manual, which incidentally is also in the haynes manual.

 

So if you fit your new discs and go down the road and find they are transmitting forces to the pedal what will you do then ?

Everything you seem to type is spoiling for an argument, not just here but every topic... why?

Can you not allow others to have an oppinion?

 

Do you not value that these companies that have been going for years have a quality department?

 

Sure they might not be worthy of machine shop use, used every day would soon fall out of calibration and wear, but for the odd use new units are more often than not going to be better than 2nd hand units without a known history.

As this is going completely off topic (again) and is turning into a bit of an "I know everything and everyone elses opinion is wrong" arguement I will draw this to an end.

 

I'll be looking to buy the gauge below following a recommendation from AC Dodd.

Ta, but I do know what disc run out is. Without removing metal you're limited to the number of ways you can refit the disc (4 bolts means another 3 goes before you're back to where you started), though I suppose you could swap new discs side to side. You'd still only need to know which moves the dial gauge least, not what it says and whether it's accurate.

 

I have to confess I'm not that much of a perfectionist. If I was, I'd probably also crawl the last 3 or 4 miles home so my discs didn't warp from residual heat soak from parking up with hot pads.

 

Minis are ever more enthusiasts cars, so there's nothing wrong with owning the best tools and setting your car up to the nth degree, but you can still enjoy them with more modest effort.

 

Since the topic is locked, it's only fair to add some advice MRA PM'd me pointing out that you can rotate the disc and drive flange in increments of one spline on the CV joint. I concede this would allow you correct any excess in tolerance across the wheel bearing more precisely . I still think it's more effort than would justify an owner-enthusiast struggling to get themselves a professional quality dial gauge.
